Awesome! I was having iPhone issues and my carrier (of course) couldn't tell me anything. I dreaded the thought of coming to a scammy shop in the mall but my experience was quite the opposite!
Staff diagnosed my phone as "healthy" after running a few tests and explained what was most likely happening. I wasn't pushed to buy anything or guilted into anything-love!
I'll be back when my iPhone decides it's time to die on me!
